WELL COMPLETION WITH MERGED INFLUX OF WELL FLUIDS

摘要

The objective of the invention is to smoothly merge influx flow streams with the wellbore flow stream so as to reduce pressure drop along the perforated section of the wellbore liner. A completion liner for a well for production of hydrocarbons is provided with angled ports through the sidewall which reduce pressure drop along the length of the liner. Furthermore, a short imperforated completion tubing for a well for production of hydrocarbons is concentrically mounted alongside substantially only the perforated section of the production tubing to cause production fluids to initially flow toward the wellhead along an annulus defined between completion tubing and the production tubing prior to exiting the annulus and commingling with fluids produced further down hole. Furthermore, a completion casing for a well for production of hydrocarbons which is provided with angled perforations through the casing sidewall which reduce flow resistance along length of the casing.
